Emulation of data processing display terminals of variable screen size on the display of a text processor.

摘要

An improvement is provided to a text processor (16) having an interactive display terminal (17). The improvement provides for a combination of said text processor (16) with a data processor (11) and means for conducting data processing sessions utilizing the data processor (11) between text processing sessions carried out by said text processor (16). During such data processing sessions, the interactive display terminal (17) of said text processor emulates a data processing terminal. The emulated display terminal is connected to the data processor (11) whereby the emulated terminal functions as a display terminal for the data processor. Further, means are provided which are operational during the data processing session to define the outer dimensions of a limited area on the display terminal to correspond to the dimensions of the data processing display terminal screen being emulated. In accordance with a more particular aspect of the disclosure, means (19) are provided in the text processing system (10) for storing data representative of the outlines of a plurality of different data processing display screen to be emulated together with means for selecting one of the plurality of stored outlines to be displayed on the emulated screen.
